HOLDING DEVICE FOR YARN BODIES Filed Sept. 1, 1932 Patented Aug. A 27, 1935 UNITED STATES HOLDING DEVICE FOR YARN BODIES Alex Luchtenberg, Wuppert'al Langerfeld, Germany, assignor to American Bemberg Corporation, New York, N. Y., a corporation of Dela- Ware Application September 1, 1932, Serial No. 631,435 In Germany October 15, 1931 2 Claims.

My present invention relates to an improved device for the holding of yarn bodies, and more particularly, to an improved holder for spinning cakes during after-treatment thereof.

In the washing and treating processes and devices now in use certain disadvantages are present. Portions of the yarn packages, particularly the inner portions thereof, which, during the washing and other after treatment, are in direct contact with the supports, are sometimes not completely and uniformly treated and/or washed. In many instances the threads are damaged and even broken during the loading and unloading of the treating apparatus. Accordingly, one object of my present invention is to provide a suitable holding device for use during the washing and after treatment of yarn, especially during washing and treating spun cakes of artificial silk.

Another ,object of my present invention is to provide an improved device comprising resilient and collapsible holding devices which may be covered with porous fabric before the yarn packages are placed thereon. These fabric coverings are preferably in the form of tubes which may be readily positioned on the holding devices.

A further object of my present invention is to provide improved yarn supporting devices which are so constructed-as to be collapsible whereby the yarn packages may be readily positioned thereon, and the holding devices thereafter expanded so as to hold. securely the said yarn packages during treatment. The supporting devices are first covered with a suitable tubular porous fabric, so that the yarn packages will not be directly in contact with'the said holding devices, and the treating liquids will reach the interior surfaces of the yarn packages at their place of suspension, and thereby insure a uniform treatment of the yarn packages. To protect the outside layers from injury, the free ends of the fabric covering the yarn supporting device mayl be pulled over the yarn packages.

These and other objects will become more apparent from a study of the following description and by reference to the attached drawing in which: a Q

Figure 1 is an end view of one form of holding device, parts thereof being shown in cross section;

Figure 2 is a side elevation of one of the holding devices. r

Referring now to the drawing, I have shown therein a preferred embodiment of my improved holding device. The yarn holding means comprises two substantially rectangularly bent wires l0, ll connected together in spaced relationship 7 by cross members l2. These cross members are provided with centrally located stub shafts l3 by means of which the holding device may be movably ,or rotatably mounted on bearings (not shown) in a treating apparatus. Each of the rectangularly bent wires is pivotally secured to the cross members by means of bearings, l5 formed at each end of each cross member. the two diagonally opposite sides of the holding device the rectangularly bent wires are provided with depending portions or hooks l6, 11 which, when theholding device is in open position, bear against the cross members and hold the same in open position.

In order toplace the spinning cakes on the holding devices, the rectangularly bent members are shifted in oppositeand longitudinal directions, namely the upper rectangularly bent wire I8, is shifted to the right and the lower one H r to the left. The shifting of the rectangularly] bent, members displaces the cross arms and the distance between the rectangularly bent wires is diminished. Thespun cakes of artificial silk are then positioned on the holding device, and I thereafter the cross arms are moved back into,

the original position, thereby supporting the in terior surfaces of the cakes.

As will be readily appreciated, the construction of the device'is very simple and inexpensive. It is also possible tomanufacture it from metal which is resistant to acids without an increase in the cost of manufacturing. The improvement of two and no more than 4 rods for the support of the yarn package is advisable. In] this manner the treatment may be performed satisfactorily and the placing and removal of the yarn packages upon the holding devices is done without damage to the yarn.

Having now described my invention as required by the patent statutes, what I desire to claim is:'

1. A collapsible supporting device for cakes and skeins of artificial silk comprising, in combination, a pair of wires each bent into rectangular form, cross members to which said wires are pivotally connected at each end to hold the same in spacedparallel relation, said wires being bent at opposite diagonal sides to form a portion contacting with said cross members to maintain said supporting device in expanded position.

2. A collapsible supporting device for cakes I andskeins of artificial silk comprising, in combination, a pair of wires each bent into rectangular form, cross members to. which said wires are pivotally connected at each end to hold the same in spaced parallel relation, said wires being bent at opposite diagonal sides to form a portion contacting with said cross members to maintain said supporting device in expanded position and means secured to said cross members adapted to be journalled in bearingsformed in a washing frame.
